If such topics are already built into the syllabus, you may wish to present your own version (or a selection) of similar guidelines at the start of the term and solicit student input, posting the list to Canvas or distributing via an updated syllabus. As the semester continues and you witness particularly constructive or problematic behaviors, you may wish to revisit and revise this list with your students.
